I use highlighting a lot when I am editing. Helps me to see words that I tend to overuse or use in clusters.
Scrivener and Word will both do this automatically if you use the Search / Find functions. (Older versions of Word use the Reading Highlight function.)
The highlighting then shows clearly anywhere where you’ve used the word. Very handy!
This is my last Christmas tip, though there may be other tips in future. I hope they’re useful to some of you writer folk out there.
